They did a complete work up which included blood work and ECG. All that came back normal. I am going through early menopause due to having a hysterectomy this past December. I occasionally have low blood pressure due to taking BP meds for migraines. The vertigo has subsided some and the palpitations are gone. I’m still extremely exhausted and going back and forth between hot and cold sweats, and not being able to sleep but for 1 hour at a time. I’m sweating profusely, and I don’t sweat for anything. Not even much during exercise. I go see my PCP on Friday and hopefully get to the bottom of all of this. I had just never heard that question asked before during an assessment for vertigo. They tested me for BPPV and I don’t have that. I’m taking Antivert to help at this time. Thank you for all of your concern and help answering my question. I’ll update Friday after I see my doc to let you all know what is going on.
